Review of #3055 code part

• Add App\Collaboration\Cart\Persistence\Mapper; TODO: document
• Add services.yaml; TODO: document the tags, use the file as example
• Remove @copyright as doc example files must be reusable by the reader without limitation
• Remove @license as no LICENSE file is distributed alongside those examples
• Rector
• Move templates to storefront theme as they depend on it and one overrides it
• Design for storefront theme a bit more
• Inherit storefront bundle's cart view to simplify its extension
• Move SQL to files to ease internal review and reuse
• Update existing include_file and hl_lines (but only that, for more about code descriptions or the use of the services.yaml, see my review of IBX-11083: Extending collaboration described in Developer Documentation #3055)
